The developers have been tight-lipped about the project so far, except for one component. Bank of America is leasing about 500,000 square feet in an office tower that’s under construction now, with an expected opening date of 2019.

“The proposed development will include up to 5,000,000 square feet, including office, hotel, retail, residential and open space components,” city staff wrote in their description of the pedestrian bridge.

For comparison, the Duke Energy Center across Stonewall Street is about 1.5 million square feet. SouthPark mall totals about 1.6 million square feet. The Lincoln Harris/Goldman Sachs plan, at 5 million square feet, would be one of the largest development projects ever uptown.

Johno Harris, president of Lincoln Harris, couldn’t immediately be reached for more information Wednesday. Lincoln Harris and Goldman Sachs bought the 10 acres that were home to the Observer and Reeves Sheet Metal for about $37.5 million last year.

In addition to the proposed pedestrian bridge, a tunnel runs between the two sides of the site, beneath Church Street. The tunnel was formerly used by the Observer to move bales of newsprint from a storage warehouse under the Church Street parking deck into the basement of the main Observer building, which fed into the printing presses.
